My invention relates to portable sewing ma chines with a luggage-type carrying case which have a drop-leaf table extension connected with the machine base and are equipped with a con-- tainer for accessories.

In a known machine of this kind, the provi sion of a drop-leaf extension and of an accessory container has the disadvantage that, when the machine is in condition for storing or carrying, the space occupied by the accessory container adds considerably to that otherwise needed so that a correspondingly larger cover or carrying case is required. In another machine, such an increase in space requirements is avoided by providing an accessory container that must be separated from the base of the machine to permit applying the machine cover.

It is an object of my invention to devise a portable sewing machine of the above-mentioned type whose work-table extension and accessory container are permanently joined with the machine base but which, when in condition for storing or carrying, requires much less space than heretofore necessary.

To this end, and in accordance wtih a feature of my invention, the accessory container is joined to the machine base so as to be tiltable as well as displaceable relative to the base. According to another feature of the invention, the drop-leaf extension of the work table is hinged to the accessory container so that the extension leaf forms a lid for the container and is likewise tiltable as well as displaceable relative to the machine base.

The foregoing and more specific objects and features of the invention will be understood from the following description of the embocliment of the invention illustrated on the drawing, in which Figure 1 shows the sewing machine in relation to the appertaining luggage-type carrying case;

Fig. 2 shows the same machine removed from the carrying case and set up for operation,

Fig. 3 is a top view of the accessory container of the machine, and

Fig. 4 is a sectional detail View of part of the machine base.

The illustrated sewing machine has a machine portion I equipped with a bottom plate 2 with which it is mounted on a base structure 3 of a hollow, box-like design. The inner side walls of the base structure have guide grooves 4 and rails I5 for receiving respective slide bars I which are firmly secured to a front plate 8 and form together with the front plate a frame-shaped drawer structure displaceable along the grooves 4 of the base structure. The drawer structure is biased into the base structure by means of springs 6 which abut at one end against a bent-away projection 5 at the inner ends of the drawer bars I. The other ends of respective springs 6 abut against'the front wall I4 of the base structure 3.

The front plate 8 of the drawer has a recess 9 which receives a handle I 0. A hinge II connects the front plate 8 with the accessory container I2. Hinged to the container is a lid I3 which when in open position forms an extension table or support for the material to be sewed. The accessory container I2 is divided into compartments I5 and H. The carrying case is denoted by I8.

When the carrying case I8 is lifted from the machine, the machine parts have at first the position shown in Fig. 1. To place the machine in condition for use, it is only necessary to seize the handle 9 and to pull the drawer structure out of the machine base against the force of the springs 6 into the positionshown in Fig. 2. During the drawer pullout movement, the accessory container I2 slides off the base plate 2 and tilts downward into the frame space between the drawer bars I and the front plate 8 of the drawer structure. In this manner, the accessory container locks itself as well as the spring-biased drawer in the position apparent from Fig. 2. When thereafter the lid I3 is opened to the position shown in Fig. 3, itforms an extension of the working surface, andthe machine is then ready for sewing.

For returning the machine to the original condition, the lid I3 is closed and the accessory container I2 lifted out of its seat into the upright position. Then the springs 6 pull the drawer frame I, 8 back into the base structure until the accessory container reaches the position shown in Fig. l.

I claim: .1. A portable sewing machine, comprising a box-'likebase structure, a frame-shaped drawer structure having a front plate and having two 'mu'tually spaced and parallel slide bars firmly secured to said front plate and in sliding engagement with said base structure, an accessory container hinged to said front plate and having a hinge axis perpendicular to the sliding direction of said drawer structure so as to be tiltable between a vertical inactive position and a horizontal active position, said accessory container having a side wall in touch with the top surface of said base structure when said drawer structure is moved into said base structure and said container in its vertical position, whereby said container can drop into the frame space of said drawer structure to the horizontal container position when said drawer structure is pulled out of said base structure.

2. A sewing machine according to claim 1, comprising a drop-leaf extension-table member hinged to said accessory container and forming a cover lid therefor, said table member being approximately fiush with said front plate of said drawer structure when said container is in its vertical position and said member in the container-covering position.

3. A portable sewing machine, comprising a box-like base structure, a frame structure horizontally movable into and out of said base structure, said frame structure having an exterior front plate and having two mutually spaced and parallel slide bars firmly secured to said front plate and in sliding engagement with said base structure, an accessory container hinged to the top edge of said front plate and having a hinge axis perpendicular to the sliding direction of said frame structure so as to be tiltable between a vertical position and a horizontal position, said container being disposed within said frame structure when said frame structure is outside said base structure and said container is in said horizontal position, and an extension table member hinged to said container and forming a covering lid for said container, said table member having a top surface substantially flush with said base top surface and being movable to a horizontal lid-open position when said container is in its horizontal position.

4. A portable sewing machine, comprising a box-like base structure, a frame structure horizontally movable into and out of said base structure, said frame structure having an exterior front plate with a handle and having two mutually spaced and parallel slide bars firmly secured to said front plate and in sliding engagement with said base structure, an accessory container hinged to the top edge of said front plate and having a hinge axis perpendicular to the sliding direction of said frame structure so as to be tiltable between a vertical position and a horizontal position, said container being disposed within said frame structure when said frame structure is outside said base structure and said container is in said horizontal position, and an extension table member hinged to said container and forming a covering lid for said container, said table member having a hinge axis parallel to said sliding member direction when said accessory container is in its horizontal position and having a top surface substantially flush with that of said base structure when said container is in its horizontal position.
